Abstract
The nozzle has a conical wall with injection orifices; the pin has a tip activated by an axial force to engage the wall and close the orifices; the tip has a truncated-cone-shaped portion having an outer surface which rests entirely on the wall, possibly as a result of elastic deformation of the outer surface; and the outer surface forms with the wall a substantially zero angle with a tolerance of 0′ to ±10′.
